COX, of Greenville, in the county of Pitt, and State of North Carolina, have invented a new and useful Improvement in Horsedower; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in theart to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in whichi Figure 1 is a top'or plan view of my improved horse-power.

My invention has for its object to furnish an improved horse-power for imparting motion to threshers and other machines; and it consists, niet, in the reel, formed by the combination of the hubarms, cross-pieces, horns, connecting-rods, swivel-screws, supporting arms, and pulleys, screw, nut, and tightening-rods with each other; second, in the combination of the pulleys and gear-wheels, by which motion is transmitted from the reel to the machine to he driven with each other, with the frame in which kthey work, and with the rope; third, in the combination of the weighted lever, ratchet-wheel, shaft, pulley, cord, sliding-frame, and pulley with each other, with the frame, and with the sliding-frame, for the purpose of holding the rope always at the same tension; fourth, in the combination of a weighted frame and pulley with the frame, with the pulley, and with the rope, to prevent the said rope from slipping upon the said pulley.

A'is the block or support to which the pivot B is attached. C is the hub of the reel, in the lower end of which is formed a socket, into which the pivot B enters, and supports the reel. D are arms, the 'inner ends of which enter mortises formed in the sides of the hub C, as shownin iig. 2. `Upon the outer ends ofthe arms D are formed tenons, which enter mortises in the cross-pieces E. The ends of the cross-pieces E are bevelled off, so as to bring therim of the reel around which the rope F passes nearer to the arc of a circle, as shown in fig. 1. G and H are horns, set near the ends of the cross-pieces E in an angling position, as yshown in gs. 1, 2, and 7. These horns G and H are placed in mortises which pass through the cross-pieces Eintersccting each other at the centre of said cross-pieces; Uponv the side of the horns G which enter from below are formed square notches, as shown' in figs. 7 and 9. The lower ends of the horns H are half cut awayas shown in g. 8; and the saidhorns are secured in place by being keyed into each other, as shown in iig. 7. I are connectingrods, upon the ends of which are formedhooks, which hook into eyes attached to the ends ofthe cross-pieces E, as shown in iig. 1, by which the said cross-pieces are connected together. vOne or more of these rods may be made with a screw and swivel, as shown at J, iig. 1, so that the rim of. the wheel may be drawn taut after the said rods I have been applied to the cross-pieces E. K are rods, upon the outer ends of which. are formed eyes, by means of which the said rods are hooked upon the hooks L attached to the upper sides of the arms D, as shown in figs. 1 and 2. Upon the upper ends of'the rods K are formed'hooks, which hook into holes formed around the edge oi' the nut M. The nut` M works upon the screw N, the lower end of which rests in asocket formed in the upper end of the hub G, as shown in g. 2. By'turning the screw Nin one direction the nut M is raised, which tightens the rods K, and -lifts the rim of the reel away from the ground. By turning the said screw in the other direction'the rim of the wheel is lowered till it rests upon the ground, or until the rods K have been so slackened that the reel may be taken apart. To prevent the reel from rocking too much upon the pivot B there is attached to the under side of every other onepoi` the arms D of the reel a downwardlyprojecting arm, L', in the lower end of which is lpivoted a friction-.wheel or roller, h which may come in contact with the ground, and support the depressed part of the reel.4` Ov is `the frame which supports the pulley and gear-wheels, by means of which the motion is transmitted from the reel to the machine tube driven. The rope F upon leaving the reel passes around the horizontal pulley P, which is designed to change the direction of the rope F and keepit at a proper tension. From the pulley P the rope passes around the vertical pulley R, and thence back to the reel, as shown.' The pulley P is pivoted tol the sliding frame S, which slides in grooves in the bars'ol and o2 of the frame o, as shown in dotted lines in iig. 4. The pulley R is attached to a shaft, which revolves in bearings attached to the bers o2 and o3. of the 'frame O, as shown in figs. 4 and 5; Upon one edge or flange of the groove'oi` the pulley R are formed teeth, which mesh into the teeth of the small cog-wheel T, which revolves loosely upon the shaftU, which lshaft has its bearings in the bars o2 und o3 of the frame O. The driving-pulley Vis secured upon the same shaft U with the cog-wheel T. Upon the hub` of the wheel Tis formed a clutch, which, when the said wheel T'is in motion, takes hold of a clutch formed upon the hub of the pulley V, as shown in fig. 5, and carries the said pulley-forward with it. But when the wheel T is stopped by the stoppage of the reel, the' pulley V continues to revolve until it has exhausted its momentum and that of the balance-wheel. The cog-wheel T i's held up against the pulley V by the action of -the coiled wire spring N', one end of which restsV lagainst the side of the wheel T, and' the other against a shoulder, u', formed upon the shaft U, asshown in fig. 5.y W is a friction-pulley, pivoted in a frame, X, which slides vertically in grooves formed in the upright bars oand o5 of the frame O, as shown in fig. 6, and in dotted lines in iig. 3. The frame X and pulley W are held in the required positionto give the proper tautness to the driving-belt by the pawl y working in the rack z formed upon the side of the frame X, ns shown in iig.

6. A. is a rope or cord, one end of which is attached to the end of the frame S, and its other-,end to the pulley B', the shaft C of which revolves in bearings in the uprights oG and o7 of the frame O. One end of the shaft C projects beyond the side of the frame O, and to it is attached a ratchet-Wheel, D. E is a lever, the lower end of which is notched to t and ride upon the end oi' the shaft C', which projects a little beyond the ratchetwheel D. This leveris also furnished with a hook, F", which takes hold of the teeth of the ratchetwheel D', as shown 'su figs. i and 3. The outer end of the lever E is Weighted. By this arrangement a constant draught is exerted uponthe frame S, keeping the rope F taut. The ratchet-wheel Dl is held in place, while the levei E' is being shifted, by the pawl P, Which is pivoted to the upright 07 of the frame O, and Works i-n the teeth of' the ratchet-wheel D', as shown in fig. 3. By varying the position or amo-unt of the weight upon the lever E the tautness of the rope F may be regulated at pleasure. G is a pulley, pivoted in a. frame, H', which frame is pivoted to thev side bars o1 and o5 of the `frame O. The free end of the frame H is weighted, and the said iframe is so placed that the pulley G may come in Contact with the rope F as it passes I is a friction-roller, pivoted to the uprights 0u and 07 ofover the pulley R- to pria-vent its slipping thereon. the frame O to serve as a guide to the rope F as it passes from the pulley R to the reel. J is a friction-roller, p ivoted to the arms K, which project from the side of the sliding frame S to-serve as a guide to the rope F as it passes from the reel to the pulley P.

1What I claim as new, and desire to secure by Letters Patent, is

. The cross-pieces E,bevelled at' their ends, and provided at both ends with horns G and H, interlocking I each wizhin the cross-pieces, in the manner described as and for the purpose specied.

2. The combination of the pulleys P and R, gear-Wheel T, and pulley V with each other,.and with the frame O and rope F, substantially as described and forthe purposes set forth.

3. The combination of the weighted lever E', ratchet-Wheel D', shaft C', pulley B, and cord A with each other, with the frame O, and with the sliding frame S, substantially' as described and for the purpose set forth.

4. The combination of the pulley G and weighted frame H with the frame O, the pulley R, and rope F,

substantially as described and for the purpose set forth.
